Pippa's insights in Celebrate: A Year Of British Festivities For Families And Friends, such as using "sharp-bladed scissors" to cut wrapping paper, have been publicly ridiculed.

Other valuable advice includes how to organise a sack race: "Everyone stands along a starting line and, on ‘Go’, players start jumping in their sacks towards the finish line. Over-enthusiastic racers will most likely get themselves in a tangle and fall."

The 29-year-old admitted to The Spectator that she had been "much teased" about the book.

"It's all good fun, I know, and I realise that authors ought to take criticism on the chin," she said.

"If I were to write a cookery book, for instance, I would be compelled to say that, to make an omelette, you have to break at least one egg" she added, defending criticism that she states the "glaringly obvious".

Pippa also joked about her most famous asset. "Maybe I should write a sequel and call it Bottoms Up? Now that could be a bestseller," she said.

The book has spawned a parody twitter account PippaTips with over 30,000 followers.

Spoof tweets include "now you can open day 3 of your advent calendar. Simply look at it with your eyes & open one with only the number '3' on it"
